A dictionary of commonly used - and often confusing! - Internet jargon...

 

Hopefully the translations, definitions and explanations of technical and computer lingo on this page will help you to speak the language of the Internet more fluently.

1xRTT (Single Carrier (1x) Radio Transmission Technology) An early wireless communication protocol for network connection of devices such as laptop computers. 1xRTT had the capability of providing data transfer speeds of up to 144 thousand bits per second .
Access
Provider
A company that provides Internet access to its customers. The customer's modem dials a phone number at the provider's location to make the connection. If the provider's number is a local call, there is no further hourly charge. The provider's fee is usually a flat monthly rate. Now more usually a broadband (ADSL) connection.
Also see Internet Service Provider ISP
ActiveX A program used to create interactive content for World Wide Web sites. It was created by Microsoft as a competitor to Java, an extremely popular programming language from Sun Microsystems.
Adobe
Acrobat
Acrobat is a file reader program which uses a format called PDF (Portable Document Format) which will display a document with the same formatting, layout, graphics and fonts used by the creator. The PDF can be viewed on a wide variety of different computer platforms. It is available free from its creator, Adobe at their Web site.
ADSL (Asymmetric Digital Subscriber Line) Newer type of data communication which delivers and receives information on current telephone lines at a much greater speed. The Assymmetric part of the name means downloading occurs faster than uploading, so this will be particularly useful for Web browsing, since the flow is mostly one way to the user. (See DSL.)
AdWare

( AD supported softWARE ) Software that is given away for "free" but causes advertising messages to appear on a regular basis.    or
( ADvertisement WARE ) Software that causes "pop up" ads on a user's computer. Adware is often installed without the user's knowledge, but sometimes with their inadvertant consent (clicking agree or accept on a licence without actually reading it - the part about AdWare is usually about 500 words into the licence) AdWare typically contains SpyWare and displays targeted adverts based on words searched for on the Web or information derived from the user's surfing habits that have periodically been sent secretly to the spyware's Web server.

Ajax (Asynchronous JavaScript and XML) Method of adding content to a web page in which javascript code in the web page fetches XML data from the server and displays it without re-fetching the entire surrounding page at the same time (hence the 'Asynchronous')
Alta Vista One of the older major search engines.
Analog
Modem
An analog modem communicates over regular telephone lines by converting (modulating) computer (digital) data into sound. At the receiving end, the data must then be converted (demodulated) back to digital form. The speed of the analog modem is very slow compared to digital modems.
Animated GIF Animated GIF allows a series of images to be displayed one after another or on top of each other, displaying a simple type of animation. The advantage of animated GIFs over other animation programs for Web pages is that the user needs nothing extra besides his browser to see the animation. See GIF.
Anonymous FTP A system to retrieve documents, files and programs from computers on the Internet which provide public access via FTP. When a user name is asked for in order to log in, type the name "anonymous", and when a password is requested, use your e-mail address.
AOL (America Online) Once the most popular of the online services. Its aggressive marketing has enabled it to leapfrog its competitors with over 20 million subscribers. AOL's purchase of Netscape made them one of the top power players of the Internet, now AOL's recent purchase of the "social networking" site BeBo makes them even more powerful.
Applet A small Java program that can be downloaded quickly and used by any computer equipped with a Java-capable browser which adds animation and interactivity to the Web page.
ARPAnet "Advanced Research Projects Agency Network," the forerunner of the Internet. The Department of Defense developed it in the late 60s and early 70s to be an information network that could survive nuclear war. See also JANET
ASCII (Stands for "American Standard Code for Information Interchange" and is pronounced "ask-ee") A system of representing text by numbers that enables various computers to display the text in a uniform way.
@Home Network A provider of Internet connection via cable rather than phone lines at speeds hundreds of times faster. The @Home service is not yet available in all markets, but it is growing at a very fast rate and demand has been heavy. Widespread use of cable modems will revolutionize the Web browsing experience because download times will be dramatically cut, meaning full motion video and stereo quality sound will become practical on Web sites.
Attachment A file that is sent along with an e-mail message, rather than as a part of the message itself. This could be a large text file that you don't want to retype in the e-mail message, or a graphic or picture.
Backbone A high-speed line or series of connections that forms a major pathway within a network, such as the Internet.
Bandwidth How much "stuff" that goes through a network connection, measured in bits per second. One text page is about 16,000 bits. A 56k modem can move about 30,000 bits each second.
Baud Rate In a communications channel, such as a modem, a baud is a variation in the signal. The baud rate is the maximum number of these variations that can occur in a second. The fastest baud rate currently available in analog modems is 56,000, hence the name "56k modem".
BBS (Bulletin Board System) Works like its real world counterpart. A place to post messages and read messages left by others by computer. Most BBS systems charge a fee to belong and, if their phone number isn't a local call, you'll pay long distance charges for as long as you're connected. The Internet's version of a BBS is Usenet News, where there is no charge.
Beta

BinHex A program that converts the binary (see above) information in a picture or graphic to ASCII, which is a text format, thus making it quicker and easier to transmit over the Internet.
Bit A bit is the smallest unit of computer data, represented by "1" or "0", whereas a byte is a combination of bits, usually 8, that represents a single character.
Bitmap A graphic image formed by a pattern of pixels or dots. Some bitmap formats are GIF, JPEG, TIFF, BMP, and PICT. Graphic images on Web pages are bitmaps.

Cookie Not chocolate chips, these are data files that let Web site operators and advertisers record the trail of sites that a person visits during a Web session as well as online purchases and transactions. The files are stored on the user's computer without his knowledge. The cookie enables the site to recognize you when you return by "branding" your browser with an electronic serial number. Some controversy is developing over whether sites should have to notify visitors when they are going to send a cookie.
Cracker A person who illegally gains access to someone else's computer or software. The term hacker is used incorrectly to mean what a cracker does.

E-Mail Stands for electronic mail, or messages transmitted electronically via computer, using an e-mail software program.
E-Mail
Address
Just as your street address is where your mail is sent in the physical world, an e-mail address identifies your Internet location for mail delivery. The address consists of a unique name or number that identifies you followed by the @ symbol and then the name of the "host" organization, which could be a business, university, or Internet service provider. Recently more & more people are getting their own personalised e-mail address instead of using the "hosts".
Emoticon (Also known as Smileys) Faces made using keyboard symbols to liven up E-Mail messages, IRC chats and Usenet newsgroup postings. eg a smile :-) tilt your head to the left, see it sideways

A helper is a separate application that is launched outside the browser when needed. Similar functions can be handled a little more simply by plug-ins which perform right within the browser.
Hierarchy The main categories of Usenet newsgroups.
Hit A term used to describe the accessing of a World Wide Web page. Even though figures are tossed around of number of hits as proof of the popularity of sites, a hit is not an accurate measurement of traffic to a site because different pages may require the browser to "hit" several times to bring the page in.

Internet Name Same as Domain name, an address on the Internet for websites & e-mails. Controlled by InterNIC
Internet
Service
Provider
ISP A company that provides Internet access to its customers. The customer's modem dials a phone number at the provider's location to make the connection. If the provider's number is a local call, there is no further hourly charge. The provider's fee is usually a flat monthly rate.
More recently an ADSL or broadband connection is used.

IRC (Internet Relay Chat) A section of the Internet where users can "chat" with others by typing messages which appear on the monitors of other users as soon as they are sent. Anyone can create a channel which is a private area for a chat. Messages can be sent one-on-one to another user or broadcast to everyone in the channel (Chatroom ).
ISDN (Integrated Services Digital Network) ISDN is a phone line that moves data digitally, a much faster way of transmitting than traditional analog phone lines and modems. Analog lines require the data to be translated from digital to analog, then sent over the line, then translated back to digital for the computer at the other end. A digital line eliminates this step. Phone companies are currently rushing to install ISDN lines which will substantially reduce access times for World Wide Web pages and download times for FTP files.
ISP (Internet Service Provider) A company that provides Internet access to its customers. The customer's modem dials a phone number at the provider's location to make the connection. If the provider's number is a local call, there is no further hourly charge. The provider's fee is usually a flat monthly rate. Now more usually broadband ADSL

McAfee's
VirusScan
A virus scanner is an absolute necessity these days, and McAfee provides one of the best. A solid, intuitive graphical interface simplifies the scanning process. VirusScan even runs in the background, allowing you to continue your work (or play) while it does it's job. The ability to configure scanning levels (specify file types), print activity logs, and the fact that McAfee updates this software very frequently, makes McAfee VirusScan a winner.
Megabyte Measurement of data -- a million bytes or a thousand kilobytes. Most commonly used to measure the working memory area of your computer, e.g., 16 megabytes used to be considered plenty, but now 32 and even 64 are becoming more desirable as programs grow in size.
